New miniature rose plant named Ruinielov

ABSTRACT

A new variety of miniature rose having dark red flowers produced on a good pot forcing plant.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was discovered by me as anatural mutation in a controlled planting of the rose known as"Ruimired", U.S. Plant Pat. No. 5,770, the disclosure of which isincorporated herein by reference. The new variety differs from"Ruimired" in flower coloring. The variety denomination of this new roseis "Ruinielov".

Among the novel characteristics possessed by this new variety whichdistinguishes it from its parents and all other varieties of which I amaware are its attractive dark red flowers borne on a plant suitable forproduction of flowering pot plants and that can be reproduced throughpropagation by cutting or by grafting. Flowers of the new variety arelong lasting on the plant. Asexual reproduction by budding and bygrafting of the new variety as performed in Broby, Denmark, shows thatthe foregoing and other distinguishing characteristics come true to formand are established and transmitted through succeeding propagation.

The accompanying drawing shows typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentdepicted in color as nearly true as it is reasonably possible to makethe same in a color illustration of this character.

BRIEF DESCRIPTION OF THE DRAWING

The photo illustration shows details of the new variety of miniaturerose.

DESCRIPTION OF PREFERRED EMBODIMENT

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticultural Society ColorChart (R.H.S.C.C.) and horticultural terminology in accordance withstandard terminology used in UPOV-approved horticultural guidelines. Theterminology used in color description herein refers to plate numbers inthe aforementioned color chart.

Parentage: Mutation (sport) of the rose variety known as "Ruimired".

Class: Miniature.

As can be seen in the accompanying illustration, "Ruinielov" isexemplified by attractive dark red flowers which open well and which arecomplimented by dark green foliage. Since flowering is nearlycontinuous, the floriferous "Ruinielov" pot plant can remainattractively in bloom for long periods when given proper care andculture.

The photo shows details of the new variety "Ruinielov". In theillustration there is shown the top of a young shoot 1; compound three,five and seven leaflet leaves, 2, 3, and 4; a side branch, 5, withthorns; a green bud, 6, showing color and a bud, 7, with slightly moresepal separation; and open blooms, 8, and 9. Also shown are flower stems10, 11 and 12 with sepals and reproductive organs.

The following further horticultural observations were made of specimensgrown outdoor in Holland.

(4) Sepals.--Longer than bud, slight to extensive foliation, mediumsepal extension.

(5) Penduncle.--Length -- medium. Aspect -- straight. Strength -- erect.Color -- medium green.

B. Bloom:

Flower.--Average size for miniature; viewed from top -- irregularlyrounded; viewed from side: (A) upper part of fully opened flower --flattened convex; (B) lower part of fully opened flower --convex.

(2) Borne.--Primarily singly, one to a stem.

(3) Form.--Ovoid at first, becoming flat; outer petals reflex and rollunder.

(4) Petalage.--Many petaled, fully double.

(5) Color.--After sepals fall and petals unfurl, predominant flowercolor is near 45A, B to 46A. Color through this range is substantiallystable, occasional white streak. Petals at flower centers may approach47B. Petals toward point of petal attachment, near 155A.

C. Petals:

(1) Texture.--Medium to thick.

(2) Appearance.--Inside velvety and outside satiny.

(3) Form.--Obovate.

(4) Arrangement.--Regularly arranged, imbricated.

(6) Persistence.--Drop off cleanly.

(7) Fragrance.--Slight to none.

(8) Lasting Quality.--Long lasting quality on plant.

REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

Arrangement and color.--Styles --medium length, yellow green; color --filaments pale yellow.

Color.--Yellow orange.

C. Styles: Even, medium length, bunched.

D. Stigma: Full, extend above anthers.

E. Hips: Small, funnel-shaped.

PLANT

A. Form: Upright to bushy.

B. Growth: Vigorous.

C. Foliage: Compound 3, 5 and 7 leaflets.

(1) Size.--Small to medium for a miniature.

(2) Quantity.--Abundant.

(3) Color.--Foliage at time of first flowering -- dark green.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side is medium glossy; under side is matte.

(6) Edge.--Serrate.

(7) Serration.--Ordinary, acuminate apices.

(8) Leaf stem.--Color -- medium green.

(9) Stipules.--Medium length, slightly bearded, light green, distinctauricle.

(10) Leaflet.--Cross section -- concave; terminal leaflet -- short,narrow, obtuse base; petiole -- short.

D. Wood:

(1) New wood.--Color -- purple.

(2) Old wood.--Color -- medium green.

E. Prickles (thorns):

(1) Prickles.--Present, quantity (main stalk) -- ordinary; form --straight and slanted downward; shape of upper side -- deep concave;shape of lower side -- deep concave; length -- medium number ≦5 mm; veryfew <5 mm; color -- tan to pale pink; position -- irregular.

(2) Bristles and glandular hairs.--Few to none.

F. Winter hardiness: Needs protection outdoors in severe climates.

I claim:
 1. A new and distinct variety of rose plant of the miniaturerose class, substantially as shown and described, characterizedparticularly by a plant suitable for growing in pots and by attractivedark red flowers which are long lasting on the plant.
